Parts for your 2009 Toyota Mark x-Exhaust gasket

2009 Toyota Mark X exhaust-gasket

Yes, the 2009 Toyota Mark X uses exhaust-gaskets. Toyota’s Electronic Parts Catalogue for the GRX130/133 chassis and the factory Repair Manual for the 4GR-FSE and 2GR-FSE engines both show gaskets at key joints: between the cylinder head and exhaust manifold (multi-layer steel), manifold-to-front pipe “donut” ring gaskets, and flat/graphite-style gaskets at mid and rear flange joints. So the exhaust-gasket is absolutely relevant to this model.

On a Mark X, the exhaust-gasket’s job is to provide a gas-tight seal wherever two exhaust components meet. That keeps noise down, stops carbon monoxide sneaking into the cabin, protects nearby components from hot leaks, and helps the oxygen sensors read correctly so the V6 runs smoothly and efficiently. A tidy seal also prevents popping on decel and keeps the vehicle within local noise and emissions rules.

They’re not a scheduled service item, but they’re a must-replace whenever the joint is disturbed—say, when swapping a muffler, catalytic converter, or removing the front pipe. Old gaskets compress and harden with heat cycles
